Presentation of Non-IFRS Financial Measures and Performance Metrics

In addition to the results provided in accordance with IFRS throughout this press release, Kyivstar Group has provided the non-IFRS financial measures Adjusted EBITDA and Adjusted EBITDA Margin (the “Non-IFRS Financial Measures”), as well as key performance indicators mobile ARPU, multiplay customers and total digital MAU.

Kyivstar Group defines Adjusted EBITDA as earnings before interest, tax, depreciation, amortization, impairment, gain/loss on disposals of non-current assets, net foreign exchange gain and other non-operating gains/losses, net. Kyivstar Group defines Adjusted EBITDA Margin as Adjusted EBITDA divided by total operating revenues. Kyivstar Group uses the Non-IFRS Financial Measures in addition to its results determined in accordance with IFRS in order to evaluate its financial and operating performance, to generate future operating plans and make strategic decisions. Kyivstar Group believes that the Non-IFRS Financial Measures may be helpful to investors because they provide additional tools for investors to use in evaluating its ongoing operating results and trends and in comparing its financial results with other companies operating in similar industries because they provide consistency and comparability with past financial performance. The Non-IFRS Financial Measures are not intended to replace, and should not be considered superior to, the presentation of the Kyivstar Group financial results in accordance with IFRS. The Non-IFRS Financial Measures may not be comparable to other similarly entitled measures computed by other companies.

The following table presents reconciliations of Adjusted EBITDA and Adjusted EBITDA Margin to the most directly comparable IFRS financial performance measures, which are profit for the period and profit margin, respectively:

Key Performance Indicators

Mobile ARPU measures the monthly average revenue per mobile user. Kyivstar Group calculates mobile ARPU by dividing its mobile service revenue (excluding guest roaming and wholesale interconnection revenue) during the relevant period by the average number of its mobile customers during the period and dividing by the number of months in that period. Mobile service revenue used to calculate mobile ARPU excludes guest roaming and wholesale interconnection revenue, as this revenue is not generated by Kyivstar Group’s customers but are proceeds received by other operators for the services received by its subscribers.

Multiplay customers are doubleplay 4G customers who also used one or more of Kyivstar Group’s digital products at any time during the one month prior to such measurement date.

Total digital MAU is a gross total cumulative MAU of applications offered. Under this metric, a single individual who is active in more than one application is counted as a separate MAU under each such application, such that the total digital MAUs may include individuals being counted more than once.
